Mk-II(A) Laser-Directed Energy Weapon

The Defence Research and Development Organisation (DRDO) of India successfully trialled the Mk-II(A) Laser-Directed Energy Weapon (DEW) system. This marks advancement in military technology, positioning India among a select group of nations with high-power laser weapon capabilities. The Mk-II(A) DEW system is designed to disable missiles, drones, and smaller projectiles with remarkable efficiency.

Laser-Directed Energy Weapons

Laser-Directed Energy Weapons use concentrated beams of light to damage or destroy targets. They operate at the speed of light, providing immediate engagement capabilities. This technology is becoming increasingly vital in modern warfare, especially against the rising threats posed by drones and unmanned aerial systems (UAS).

Capabilities of the Mk-II(A) DEW System

The Mk-II(A) system demonstrated its effectiveness by engaging fixed-wing drones at long ranges and successfully neutralising multiple drone attacks. It can target enemy surveillance systems and antennae with precision. The system’s rapid engagement time and lethal accuracy make it a formidable counter-drone solution.

Cost-Effectiveness of DEWs

One of the key advantages of the Mk-II(A) DEW is its cost efficiency. The cost of operating the system for a few seconds is comparable to that of a couple of litres of petrol. This affordability positions DEWs as a long-term alternative to traditional kinetic weapons, especially in scenarios involving low-cost drone threats.

Technological Innovations

The Mk-II(A) DEW employs advanced radar and Electro-Optic (EO) detection systems to identify and engage targets. Once a target is detected, the laser beam can penetrate and cause structural failures. This capability reduces reliance on expensive munitions and minimizes collateral damage, consideration in modern warfare.

Future of DEWs in Military Operations

As unmanned aerial systems proliferate, the demand for DEWs is expected to increase. The Mk-II(A) system is anticipated to replace traditional missile defence systems due to its operational simplicity and cost benefits. Military organisations worldwide are recognising the need for effective countermeasures against drone swarms and asymmetric threats.

Development and Collaboration

The Mk-II(A) DEW was developed by DRDO’s Centre for High Energy Systems and Sciences (CHESS) in Hyderabad, in collaboration with various labs, academic institutions, and Indian industries. This collaborative approach puts stress on India’s commitment to enhancing its defence capabilities through indigenous technology development.

Testing and Validation

The successful trials were conducted at the National Open Air Range in Kurnool, Andhra Pradesh. These tests validated the system’s operational capabilities and its potential impact on future military engagements.

Global Context

India’s advancements in DEW technology come at a time when many nations are exploring similar capabilities. The growing prevalence of drone warfare necessitates innovative solutions for defence, making India’s developments critical in the global military landscape.
